Application filed August 2, 1919. Serial No. 315,000.

To all 'whom t may concern:

Be it known that we, BERNARD LIBERMAN, LEON LIBERMAN and WILLAM M. REICHART,

all citizens of the United States, and all pleted cigar by the addition of the usual wrapper in a subsequent operation. Our present invention relates more particularly to improved mechanism for rolling a measured quantity of tobacco within a binder to4 form the cigar bunch. The principal object of our present invention is to provide im.

proved mechanism for the abovementioned purpose, which is so constructed and arranged whereby a bunch will be produced which will be smoothly rolled and in which the tobacco will be evenly and uniformly distributed throughout the bunch. A further object of our invention is to improve the details of construction of such machines, to render the same more simple, etlicient and certain in their action. j Y

The nature and characteristic features of our invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part hereof, in which:

Figure 1 is a view partly in side elevation and partly in section of a portion of a cigar bunching machine embodying the main fea- Y tures of our present invention; j

Fig. 2 is a fragmentary detail view Vof .a portion of the apparatus shown in Fig. 1, but with certain of the iparts in` a forward operative position; l j Y Fig. 3 is a top or planview, enlarged, of the bunching table and its associated parts; Fig. lY is a longitudinal section of the bunching table taken on the line 4-4 of Fig. 3; and

Fig.v 5 is a transverse vertical section thereof taken on thev line 5-'5 of. Fig. 4.. `Referring to the drawings, in the particular embodiment rof my invention therein shown, the bunching machine is yprovided with side-frames 10 upon which the various parts thereof are supported and mounted. The vmain driving shaft 11 is journalled 'in suitable pillow blocks 12 which are supported on the side-frames 10. Connecting the side-frames 10 is a cross-bracket 13, to

which the bunching table 14 is integrally j attached, v-and from which it projects forward in the front-of the machine. The bunching table 14: is provided at the front end thereof with V.a portion which extends forward as at 15 and then downward as at 16 forming a bracket for the support of the front ends of a pair of slide-rods 17 ,the

rear ends of which are secured in the transversely extending connecting frame 13 above referred to. The rods 17 constitute slide-ways upon which a frame or carriage 18 is slidably mounted and is adapte-d to be reciprocated thereon.

The frame work or carriage 18 is provided with a rearwardly extending lug 19, to which a connecting rod 2O is pivotally connected.Y The connecting rod 20 comprisesv a member 21 at each `end thereof which is provided with a suitable ear for making the pivotal connection, and these members 21 are interiorally threaded and engaged by a bolt 22. The ends of the bolt 22 are respectively provided with right and left hand threads, whereby the length of the rconnecting rodf20 may be varied and thus provide a means of adjustment for varying the final positions, at the front and rear respectively, of the framework or carriage 18. The bolt 22 ymay be provided with suitable lock-nuts 23 to maintain the con necting rod 20 in its proper adjusted length.

The rearV end of the connecting rod 20 is pivotally connected to one arm 24; of a bell crank lever which is pivotally mounted on a shaft 25 which -issupported by the sideframes 10 o-f the machine. The other arm 26 ofthe bell crank lever is provided at its end with a slot 27 in which a bolt 28 may be adjustably mounted. The bolt 28 forms a means vof pivotal connection for a con-A nectingjrod Y29, the other end of whichr is pivotally connected, as at 30, to the free end of a lever 31.

The lever 31 is pivotally mounted on a transverse shaft 32 which is suitably supported by the side-iframes 10 of the machine. The lever 81 also carries a cam roller 83, which is engaged by a cam groove 34 oi' a cam 85 which is mounted on the main shaft 11 and is constrained to rotate in unison therewith. The contour or shape of the cam groove 34 is such as to cause the reciprocaticn of the framework or carriage. 18 at the proper time during each rotation of the main shaft 11, this motion being transmitted from the cam 85 through the medium ci' the lever 31, connecting rod 29', bell crank lever arms 26 and 24, and the connecting rod 20. lt' will be noted that they adj:ust.

ment of the bolt. 28 inthe slot 2770i` the arml 26 of the bell crank lever aiiords a means for varying' the: extent of the longitudinal movement of the framework or carriage 18;

The reciprcoating framework` or carriage 18 is provided on each side with an arm 36, which arms extend upward on each side of the bunching table 14 and have' their respective upper ends slotted as at 37. In each slot 87 there is mounted the end of a bolt 38, provided with nuts 39' on each side ot the arm 86, whereby said bolt 38 may be vertically adjusted in the slot 37. The boltr 88 constitutes a journal for the bunching roller 40 which is rotatably mounted thereon.

The bunching table 14 is provided with a transverse channelv or pocket 41 located im# mediately forward ofthe rear position of the bunching roller 40. An apron 42 is also secured to the bunching table 14 at the irontand rear respectively. rlhe means for securing the apron at the rear comprises a transverse bar 48 which is attached` to the trame 13 by means of screws 44 and serves thereby to clamp the rear end of the' apron 42.

The front end of the apron 42 is secured to the forward end of the bunching tablel 14 by means of transverse bar 45, which is also attached to the bunching table 14 by means of screws 46. The' screws 46 are located beyond the side margins of the apron 42 so that by loosening the same, the front end ot' the apron 42 which passes beneath the bar 45 may be adjusted to thus vary the size of the rolling pocket which is formed beneath and to the rear" of' theburro-li'-` ing roller 40 in the usual manner during the' operation of the machine.

The apron 42 at the' rear is substantially' oi the full width of the builiching table' 14, but at the 'forward end, that is to say, that portion of the apron which rests on the launching table proper. is; relatively narrow' being of a width slightly lesethan the length of the cigar bunch to be rolled on. the table. Arrangedon each side ofi the nar; row portion of the apron -42 is a 47, which bars' extend along the sidomargins of the narrow portion of the apron 42 and have inclined upper surfaces (see Fig. 5), these bars 47 constitute means completing the length of the rolling portion of the device, it being noted that the binder of the cigar bunch, co-acting with the apron 42 and the bars 47, will tend to shape the bunch to the`v proper' contour and evenly distribute themtobacco therethrough.

The end forming bars 4l' are adjustably secured to the top ofV the buncning table 14 by means of bolts 48, which bolts 48 are provided at their lower ends with thumb4 screws 49, the bolts 48 passing through the slots 50 in the bunch-ing' table 1 4. vThe slots 50 are arranged transverse to the longitudinal extension. of the launching table 14 to thus permit the end forming bars- 47 to be adiust'ed sidewise to contorni to the lengthv of the bunch whichy is formed on the table 14. The b'ar 45 which clampsl the liront end of the apron 42 to the table 14; is provided with a spring-clip 52 which receives and clam-ps the completed bunch at the end. ot the forward movement of the roller 40 until the-operator has* a-n opportunity to remove the same therefrom. y

In order to smooth out the binder as the same is rolled into the bunch, there is provided a brush which, in the rearward position of the reciprocating parts, is located immediately infront of the channel or pock' et 41 of the bunching table 14. The brush 60 is provided with a bach portion 61 which is adjustably mounted on a` transversely en tending plate 62, the means of attachment comprising screws 63,v which pass through slots 64 in the plate 62.y The plate is provided at each end with downwardly depending ears 65 secured to arms 66 as at 67. Each arm 66 is provided at its lower end with a pivot screw 68 which passes through an'upwardly inclined slot 69 in an ear TO extending from the lower portion ci the reciprocating carriage 18.

Arranged on each side of the table 14 is a coil spring Z1 which is connected at one end to the link 66 at a point midway the eX- tremities of said link, and at its other end to a portion of the reciprocating carriage 18', nennt-ily,l the upwardly extending arm 3G, which is provided on each side of said reciprocating carriage 18 to support the bunch' ro-ll 40. Oneach side of the bunch table 14 adjacent the channel or pocket 41 there is provided an outwardly extending stop-'pin 72' which is encountered by the lirnlr 66 when the reciprocating carriage 18 is in its rearward position, and serves to retract the brush. 60 away. from the bunching roll 40 while the tobacco which forms the body ot tl'le bunch is being deposited in place.

Itv now bev noted that the springs' 71 serve lto cause the brush 60 toA contactwith the binder at that portionot the apron 42 which is immediately over the bunch roll 40 Sli Illu

during thejforward movement of the reciprocating carriage 18 and the parts carried thereby, this brush 60V as before stated, servf ing to smooth out the binder during the rolling or bunching operation. In order to regulate the tension with which the end of the brush 60 thus contacts with the apron 42 and the binder arranged thereon, there are provided adjusting screws 7 5 which are Vrespectively mounted in the upwardly extending arms 36 of the reciprocating car-A ticularly when the same constitutes a por. ktion of a completen machine wherein `the various parts are co-ordinated with other mechanisms whichl function at related periods.` To prevent the aforesaid improper confining of the bight of the apron Vunder the rear of the roll 40, there is provided a transverselyextending bar 80 which is attached by means of arms 81 to the upwardly extending arms 36 of the reciprocating table 18. 'Ihe bar 80 is located to the rear of vthe bunching roll 40 a sufficient distance to prevent lany portion of the bight of the apron 42 from passing beneath the bunching rollerv 40 during the rearward Vmoving of the carriage 18. f

The operation of,V the machine will now be readily understood. As before stated, the main shaft 11 makes one complete revoW lution for eachY cigar bunch formed by the machine. As the shaft 11 rotates, after the cam 3 5 arrives at thek proper"` angular loca` tion, the lever 31 will thereby 4be actuated, causing the outer end thereof to be depressed and, through the intermediary of the connecting rrod 29, bell crank lever arms 26 and 24, and connecting rod 20, the carriage 18 will be moved forward on the slideways formed by the rods 17. In this man` ner, the roller 40 which is carried by the arms 36 of the carriage 18 will be moved forward over the table 14.

However, previous to the forward movev, ment of the bunching roller 40, the binder will have been deposited over the' brush, and so as to project partly upon the apron 42, immediately over the channel 41. A. measured quantity of tobacco which is to constitute the filler of the bunch is also deposited upon the apron and upon the pro'- jecting end of the binder. As the ller is de osited, either manually or by means of otllfer mechanism, the construction of which forms no part of the present invention however, the apron 42Y is depressed into the channel 41 of the bunching table 14. Y

It will be seen that as the roller 40y adlvances over the table 14, the portion of the apron which contains theiiller and a projecting end of the binder will be caught in a'bight which will be formed beneath and to the rear of the bunching roller 40, and as the roller continues to advance over the table14, the filler and binder will be rolled to the completed bunch which will thereafter be Vdeposited in thel spring clip 52 which is provided at the frontV end Vof the bunching table 14.

. During the first part of Vthe forward movement of the bunchingV roller 40, the brush will be given a relative rearward movement towards the bunching roller 40, carrying a part of the binder which lies over it into close proximity to the bunching roller 40. The rearward movement of the' brush 60 towards the roller 40 is caused by the tension of the springs 71 which will cause the pivot screws 68 carried at the lower ends of the arms 66 to slide in the upwardly inclined slots 69 of the lugs or ears 70, and, when the pivots 68 reach the end of said slots, the upper portion of the arms 66 which carry the brush 60 will then be swung towards'the roller 40. This causes a slight elevation and tilting of the brush towards the roller. The tension with which the brush 60 willY press against the binder is limited or regulated by means ofthe ad justing screws 75 which are carried by the arms 86 and which are encountered by the lugs 76 carried by the arms 66. Y Y

As before stated, the rear portion of the apron 42,is of substantially the full width of the bunching table, while the forward portion thereof is of a width somewhat less than the length of the bunch which is formed on the table. In connection with the narrow portionY ofY the apronr42, the plates 47 are provided which as before stated, have inclined upper surfaces which co-act with the ends of the binder which extend beyond the side margins of the narrow portion of the apron. The' plates 47' serve to prevent length-wise sliding of the filler within the bunch and will maintainV the proper tapered shape of the ends of the bunch.

After the bunch has been rolled and de posited within the springclip 52, the carriage 18 will then start on its rearwardv movement, and when the links 66 which carry the brush 60 encounter the pins 72, the brush' 60 will thereby be raised away from the bunching roller '40 as the same continues to pass to its rearward position.

The apron 42 is made of the usual flexible material, and as the roller 40 in its movement to the rear passes over the chaniao n fproper functioning of the machine.

nel il there will ordinarily be a tend ency of the apron to be improperly caught beneath the roller 40, which action would subsequently interfere with the To overcome this diiiiculty, the bar 8O is provided, the same extending transversely some distance to the rear of the roller 40, and raised sunriciently above the rear portion of the table to enable the apron 42 to be freely released from under the same.. When the carriage 18 is in its rearward position, the transversely extending bar 8O will also serve to temporarily maintain the apron 42 above the channel il so that the binder may be more readily positioned thereon by the operator of the machine.

Having thus described the nature and characteristic features of our invent-ion `what we claim as new and desire to secure by Letters Patent is: Y

l. In a cigar bunching machine, the combination of a bunch-rolling table', an apron and cooperating roller, a reciprocating roller support, a brush for cooperating with the apron, in rolling the binder on the bunch, means for automatically7 positioning the brush and roller a required distance apart to permit depositingl the filler between them, means for actuating the brush to cause its movement toward the roller during preliminary movement of the roller and adjustable means for limiting said actuation.

2. In a cigar bunching machine, the combination of a bunch-rolling table, an apron and cooperating roller, a reciprocating roll-v er support, and an apron engaging bar eX- tending parallel with the roller and to the rear thereof and movable with the reciprocating roller support.

3. In a cigar bunching machine, the combination of a bunch-rolling table, an apron and cooperating roller, a reciprocating roller support, a brush for cooperating with the 'apron in rolling the binder on the bunch, means for automatically positioning the brush and roller a required distance apart to permit depositing the filler between them, and means for automatically actuating the brush to move toward the roller simultaneously with the preliminary movement of the roller, and adjustable means for limiting said brush actuation, and for maintaining an adjusted relationship between brush and roller when moving together.

4. In a cigar bunching machine, in combination with the usual bunch rolling table, apron, cooperating roller and reciprocating roller support, a brush for cooperating with the apron, brush-supporting arms having pin and slot connection with the reciprocating support and spring controlled, a stop on the stationary table and an adjustable stop on the reciprocating support for engagi-ng a brush supporti-ng arm, one stop effective in certain positions of the reciprocating support and the other stop effective in other positions of said support.

5.- In a cigar bunching machine, in com bina-tion with the usual bunch rolling table, apron, cooperating roller and reciprocating roller support, a b-rush for cooperating with Vthe apron, brush-supporting arms having pin and upwardly inclined slot connection with the reciprocating support and spring controlled, a stop on the stationary table and an adjustable stop on the reciprocating support for engaging a brush supporting arm, one stop effective in certain positions of the reciprocating supportfand the other stop effective in other positions of said support.

In testimony whereof we have hereunto signed our names.
